We have now completed the critical operation period for the HISAKI (SPRINT-A) after we successfully performed essential events including the planned orbit insertion, solar array paddle deployment, and sun acquisition.

JAXA will take about two months to further confirm the status of the HISAKI (SPRINT-A) such as verifying the high-precision attitude control function that is imperative for planet observations.

We would like to express our sincere appreciation to all the parties and personnel concerned for their support and cooperation with the HISAKI (SPRINT-A) launch and tracking control operations.
